Rows for scanned networks not yet in breadcrumbs' saved config were
both dimmed and disabled (set_sensitive(false)), so there was no way

GitHub Actions self-hosted runners need per-repo registration on a
personal account; Forgejo Actions' runner already serves every repo
with zero setup. Moves release publishing there (dl.breadway.dev stays

GITHUB_TOKEN) and adds a mirror workflow to keep GitHub in sync
automatically.
